SANCTUARY LAMP.

Application filed May 2%,

This invention relates to sanctuary lamps and my object is to produce as an improvement over my copending application for patent for sanctuary lamp, filed June 26, 1922, Serial No. 570,992, a wick and wick support so arranged that the wick may be readily transferred from vessel to vessel without chance of breakage.

Another object is to produce a wick so arranged and supported that a small quantity of the oil will be raised above the normal oil level into close proximity to the flame for the better gasification of such oil, as it is to be understood that this invention is adapted to be usedin the burning of vegetable oils which are heavy and do not readily vaporize.

A further object is to produce a device of the character mentioned in which a pair of wicks are employed in close proximity to each other thereby providing means by which the chance of the formation of a crust so heavy as to extinguish the flame as the oil level is lowered by the gradual consumption of oil, is efficiently overcome.

With the objects named in view, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which Figure 1 is a section taken through an oil containing vessel and illustrates the burner of the invention in operative position;

Figure 2 is a view similar to that of Figur. 1, but at right angles thereto;

Figure 3 is a top plan view of the same;

Figure 4 is an enlarged side view of the flame as it will appear when burning from a slanting wick; and

Figure 5 is an enlarged View of a double wick when in a vertical position, although this view as to the position of the oil level is equally applicable to a slanting wick.

In the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 illustrates a suitable containing vessel which is adapted to be filled with any suitable or preferred oil 0.

The wick support comprises a base portion 2 resting on the bottom of the vessel and formed on its underside with a series of wick-engaging notches 3, an upright portion 4 formed at its upper end with a hook 5 for engaging over the top edge of the vessel, a

handle 6 for ease in transferring the Wick support without danger of soiling or injuring the hands or clothing or injury to the wick, and a horizontal bar 7 in vertical alinement with the base 2 and carried by the upright st in. the plane of the top of the vessel. The bar 7 is formed in its upper-edge with a series of notches 8 for wick-engaging purposes. The type of wick support, as abovedescribed, is immaterial, but is illustrated for convenience and also to show one method of securing adjustability of the wick as will be explained hereinbelow, it being noted that the notches 3 and 8 are spaced equal distances apart and extend from dian'ietrically opposite sides of the vessel to a point in vertical alinement with the vertical axisthereof.

The wick 9 of the invention is of non-conibustible character and comprises .a wick encircling the arms 7 and 3 and in engagement with a notch in each of said arms, the ends of the wick being tied together as at 10 above the arm 7 or secured in any other suitable or preferred manner. It will be evident that with the construction described, a pair or" parallel wicks extending through the oil in the vessel, is in effect produced, and that the same result would be obtained by utilizing a pair of short wicks in place of one long wick.

When a pairof wicks are spaced a relatively slight distance apart, as described, the oil level, through the formation of a concave meniscus on both wicks, will be caused to as some a relatively higher position between the wicks, as indicated at 11, and a quantity of oil is brought'nearer the flame and is more readily heated to a high temperature, becomes thinner and more readily ascends the wicks into the flame where it is gasified and burned. It is desirable in this connection to point out that due to the raising of the oil level, it a crust is formed on one of the wicks, the oil will be caused to rise above said crust bet-ween the wicks, and feed the flame above the crust without hindrance. It has been found that it the pair of wicks are allowed to contact with each other, no

separate meniscus will be formed on each wick as there will be no space for such ton mation, and the oil level will, therefore, not be raised to a higher level than that due to a single meniscus, the two contacting wicks in effect forming but a single wick of greater diameter.

The angle of the Wicks in the vessel may be readily changed by adjusting them along the base 2 and bar 7, to suit the consistency of the oil to be burned, and the length of time desired for its consumption. It has been found. due to the better upward flow of the oily thinned between the wicks, as mentioned that even it a crust forms on one of the wicks impeding upward flow of the oil, as mentioned, the flame will follow the other wick and will consume such crust as soon as the flame has descended sufficiently to expose the crustto the action of the white part of the flame.

It has also been found, although the flame will descend properly when the wick is in a vertical position, that a slight soot deposit is formed on the wick after the passage of the flame. l/Vith the character of oil used for sanctuary purposes, combustion takes place around the side edges of the flame, the center being gas, and its upper part filled with soot, and, therefore, relatively cool. This fact leads to the soot deposit mentioned and destroys the wick for further use until it has undergone proper manipulation for the consumption of. such soot.

When the wick is inclined, however, see Figure 4, the wick extends through the flame at an angle, and, therefore, passes through the white side edges of the flame where the combustion takes place and all soot or carbon deposits are consumed. The wick after use in an inclined position is as clear of soot and carbon deposits as when first used.

It is also to be understood that a non-combustible wick of the type illustrated in this application, is of such nature that it is comparatively fragile after being subjected the first time to the action of the flame, and because of this it is desirable to supply a supporting means of such nature that the wick may be readily transferred from one vessel to another without necessitating physical contact or handling of the wick.

From the above description it will be apparent that I have produced a device which possesses all of the features of advantage set out as desirable, and while I have described and claimed the preferred embodiment of the same, it is to be understood that I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim:

1. A sanctuary lamp comprising an oil containing vessel, a pair of parallel wicks close enough to conjointly support combustion at a single point in close proximity to the surface of the oil, and extending through the oil in said vessel, and means securing the opposite ends of said wicks ad jacent the bottom and top of said vessel respectively.

2. A sanctuary lamp comprising a vessel, a base member in said vessel, a bar substantially in alinement with and parallel with the mouth of the vessel, and a double wick encircling said base member and bar, the two parts of the wick being parallel and spaced apart in sufficiently close relation to conjointly support combustion at a single point in close proximity to the surface of the oil. 7

3. A sanctuary lamp comprising a vessel, base member in said vessel, a bar substantially in alinement with and parallel with the mouth of the vessel, a series of notches formed on said base member and bar, and a wick in engagement with a notch of said base member and bar and encircling and spaced apart by said members.

4. A sanctuary lamp comprising a vessel, a base member in said vessel, a bar substantially in alinement with and parallel to the mouth of the vessel and in vertical alinement with the base member, and a wick encircling said base member and bar and extending diagonally through the vessel, in sufliciently close relation to conjointly support combustion at a single point.

5. A sanctuary lamp comprising a vessel, a pair of parallel wicks extending through said vessel. and. means adjacent the bottom and top of said vessel respectively securing and holding in close proximity to each other said wicks whereby combustion may be conjointly supported by the wicks in close proximity to the oil adapted to be received by said vessel.

In witness whereof I hereunto aflix my signature.
